When you are looking at fasteners springs industrial hardware, the two products in front of you are almost opposite jobs: one is a heavy antique press meant for shop work, and the other is a commercial deadbolt meant for door security. You probably will not buy both in the same trip, so the real question is which one matches your immediate need.
Quick verdict
If you need to secure a commercial or residential door, the Commercial Single Cylinder Deadbolt Universal Hardware Industrial Duty UH40055 is the clear choice at $19.95. If you want a substantial vintage industrial press for a workshop, the Heavy Duty Antique United-Carr DOT Fastener Co M239 Industrial Cast Iron Press at $125 is the more interesting piece of equipment. The price spread is about $105, and that difference reflects two entirely different uses.

Product notes
Heavy Duty Antique United-Carr DOT Fastener Co M239 Industrial Cast Iron Press
The selling point here is substance: a cast iron industrial press from United-Carr / DOT Fastener Co., with a steel mandrel and the M-239 model designation. It is a used piece, made in the United States, and listed without dies or other parts. That means the press itself is the main event, but you will need to source any extra tooling separately if your work depends on it. For someone who wants an antique industrial press with heavy cast iron build, the M239 delivers the mass and old-shop character you cannot get from a small lock. The catch is scope: it is a specialized machine, and the listing is for the press alone, without dies or other parts, so plan to supply those separately.
Commercial Single Cylinder Deadbolt Universal Hardware Industrial Duty UH40055
This is the practical security buy. The Universal Hardware deadbolt is rated for both commercial and residential use, includes an ANSI Grade 1 security designation, and comes with two keys and a square corner deadbolt strike. The assembled trim measures about 1 inch deep by 2.5 inches high and wide, with a 2-3/4 inch backset, which gives you a compact package for a door lock installation. It is a new open-box item, so the lock itself is unused. The limitation is scope: as a single-cylinder deadbolt, it is focused on door locking rather than the heavy workshop duties of the other item. If your project is about securing an entry, this is the product that fits.
Final choice by use case
Choose the United-Carr DOT M239 press when your need is an antique industrial press for a workshop and you are willing to source any missing dies or parts separately.
Choose the Universal UH40055 deadbolt when your need is door security and a single-cylinder lock is the right fit for your entry.
